After descending more than 2,000 meters in the cave, and a strand of red flames with thin hairs could be faintly seen on the cave wall, Zhang Yuan saw that a hole with a radius of three meters appeared on the cave wall, and in front of the door sat two Taoist children in red robes sitting cross-legged, sitting cross-legged on a cyan jade board at the entrance of the cave with sweaty faces.

Baoyun Lao Dao pulled Zhang Yuan and rushed into the entrance of the cave, walked to the depths of the cave, and sat down in a vast stone room with a radius of nearly 100 meters, and then said with a smile: "I don't know the old way, what can I do to help Xiaoyou?" Zhang Yuan silently took out three pieces of paper from his sleeve, flicked his fingers, and flicked the pieces of paper to Baoyun Lao Dao. Baoyun Lao Dao took the piece of paper casually and glanced at it quickly. Suddenly, Baoyun Lao Dao jumped up from the futon and screamed loudly: "God, is this the Dan furnace?" Where is the Dan furnace up to 100 meters high? How much material does this cost 616161616161 this? ”

Zhang Yuan looked at Baoyun Lao Dao calmly, and said lightly: "That's right, the specially made Dan furnace with a height of 100 meters can produce 10,000 Dan grains in one furnace!" ”

"Ten thousand pills in one furnace?" Baoyun's eyes are green! He spun around the stone room a few times, suddenly slapped his thigh hard, and roared loudly: "His grandmother's, the poor Dao will go out and lose the family belongings today, and refine this Dan furnace for you!" ”

Baoyun Lao Dao took off his robe, put on a short green robe, and stood at the door of the cave mansion frantically directing his disciples to prepare materials. He waved his arms and shouted, "Hurry up! Hurry up! There are also 30,000 catties of fire essence iron! Come on, come on! Well, well, why didn't you send five hundred catties of lava refining iron on the material list? What do you guys of waste do? Fast! ”

Up to 100 meters, a special Dan furnace that can produce 10,000 Dan grains! As soon as Baoyun Lao Dao thought of the Dan furnace that Zhang Yuan had described to him, he was extremely excited.

A few spiritual lights fell at the entrance of the cave, and several Kunshan faction elders such as Lei Yun, Qingyun, and Wei Yun hurriedly fell and strode into the cave. Lei Yun casually brushed aside the two disciples who were bowing in front of him, and asked loudly, "Senior Brother Baoyun, what are you doing here?" The materials mentioned on the signal talisman you sent just now, those ordinary Five Elements Elites and Xuantie, Xuantong, and Purple Gold are just that, and they can be refined every year with a little effort. But those rare materials, you use thousands of catties and hundreds of catties, what do you want to refine? ”

Baoyun Lao Dao was hurriedly checking the materials sent against the material list handed over to him by Zhang Yuan, and when he heard Lei Yun's question, he casually gestured towards Zhang Yuan and said loudly: "The main master is over there, you go and ask him!" Hmm, there is still a lack of demon pills that are more than 1,000 years old fire attribute monsters that are the heart! Go get it! Hmm, my God, ninety-nine eighty-one thousand-year-old demon pills! How much is there in the treasury? And this, and this, it's just too much! ”

Lei Yun, Qing Yun, and Wei Yun heard the materials reported by the Baoyun Dao people and the number of units that followed, Zhang Yuan was a little strange to find that Lei Yun, Qing Yun, and Wei Yun, the top masters of the Yuan Shen Period, seemed to be a little fluttering. He looked at the three people who walked towards him in astonishment, and thought in surprise: "The ancestor of my Hundred Herb Sect has spent hundreds of years of hard work, and if he didn't gather these materials, the Wandan furnace he designed couldn't be refined. But with such a big fortune as the Kunshan faction, can't it still gather so many materials? ”

At the door of the cave, the Baoyun Dao man suddenly screamed, "Oh my God! Thirty-six pieces of immortal legend five element stones! It is just full stock! "It's amazing, there is already a Yuan Shen stage cultivation, and even the Thundercloud Dao people who have a faint tendency to break through to the next realm have weak legs, and they almost stumble to the ground. Fortunately, Qingyun's attention beside him was almost all on him, and when he saw that Lei Yun's face was wrong, he immediately reached out and hugged Lei Yun's arm, which was able to stabilize Lei Yun's body. Lei Yun glanced at Zhang Yuan, who was slowly standing up, and awkwardly withdrew his arm from Qingyun's tightly wrapped arm, and coughed vigorously.

Qingyun slowly withdrew his hands and lowered his head gloomily. Wei Yun Lao Dao and the other two Kunshan Sect elders raised their heads high, as if they hadn't seen this little movement between Lei Yun and Qing Yun at all. Zhang Yuan saluted indifferently, and simply greeted Lei Yun: "Junior Zhang Yuan, I have seen Lei Yun in charge." ”

The people of Thundercloud Dao walked quickly in front of Zhang Yuan, and was about to say something, when Baoyun Lao Dao at the entrance of the cave suddenly screamed again: "Ah...... No! Why didn't I see this thing just now? Still need 10,000 catties of 100,000 years of fire essence chalcedony? Oh, my God! ”

Hearing such an outrageous request, Lei Yun Lao Dao's face twitched violently, and his kind face was actually distorted and hideous. He smiled dryly at Zhang Yuan and said, "Zhang Xiaoyou, Master Zhang, although the list you opened in the medicine hall is a bit larger, my Kunshan faction can also bear it." But the list of materials you opened in the instrument hall is really a bit shocking, I don't know what Xiaoyou means? ”

Zhang Yuan looked at Lei Yun Lao Dao and said lightly: "The Wandan Furnace was created by the ancestor of the Divine Medicine Sect of my Hundred Herbs Sect thousands of years ago. "Divine medicine? Wei Yun Daoren's alchemy tightened, and he asked urgently: "Is it the ancestor of the divine medicine who created the 'Shengyuan Immortal Pill' formula?" ”

"Yes!" Zhang Yuan nodded lightly and said lightly: "It's just that the Divine Medicine Patriarch has achieved success in the Dan Dao, but the real experience of the Patriarch is in the spirit of alchemy, the technique and the Dan Furnace Dan Array. Wandan furnace, a collection of the ancestor of the divine medicine of the life of the Dan Dao, Dan Jue, Dan array, is wonderful, not only the magic weapon of alchemy, but also the spirit weapon of attack and defense. ”

"Spirit Weapon!" Lei Yun, Qing Yun, Wei Yun and the others gasped, and Lei Yun smiled bitterly: "Now in the cultivation world, I'm afraid that no one can refine spiritual weapons anymore. Lei Yun looked at Zhang Yuan with blazing eyes, wanting him to give a reasonable explanation. So many precious materials have been consumed, not to mention refining spiritual weapons, even refining immortal weapons is enough, but now that no one in the cultivation world has the strength to refine spiritual weapons, wouldn't it be a waste of so many materials? Instead of wasting these extremely precious materials on a magic weapon, it is better to combine them with other ordinary materials to create tens of thousands of more practical flying swords and treasures.

"This Dan furnace can absorb the aura of heaven and earth and continue to evolve." Zhang Yuan's deep gaze became extremely deep, although the people of Thundercloud Dao knew that Zhang Yuan's cultivation was extremely weak, but they actually had an illusion that they were unwilling to look at Zhang Yuan. Zhang Yuan's eyes were filled with a kind of profundity that only an old man with extremely rich experience and even extremely vicissitudes of life had, he looked at Zhang Yuan in a daze, and after a long time, he slowly asked: "The Dan Dao Mental Method of the predecessors of the Divine Medicine Son is said to be only recorded in the secret books of the Alchemy Mahayana. Could it be 616161616161 that you have already comprehended the Mahayana secret book of alchemy? But how can you have that kind of fate? Alchemy Mahayana cheats, this is a treasure book that only the core deacons and elders of the Hundred Herbs Sect are qualified to participate in, you ......"

Wei Yun Dao was also stunned, and he muttered to himself: "Alchemy Mahayana cheats? Zhang Yuan just nodded slightly, his lips pursed slightly, and he said in a deep voice: "It's the alchemy Mahayana secret book." ”

Zhang Yuan's words stunned the elders of the Kunshan faction. A disciple of the Hundred Herb Sect who has the secret book of alchemy Mahayana in his brain and a disciple of the Hundred Herb Sect who does not have the secret book of alchemy Mahayana in his head is completely different. Zhang Yuan, who does not have a hundred herb sect, is just a friend of Kunshan who is sent out of the hundred herb sect, and he is supported in the name of a guest qing, and he does his best. And Zhang Yuan, who has the alchemy Mahayana cheats in his head, is fully qualified to become the guest worship with the highest grade in the Hundred Herbs Sect!

The Alchemy Mahayana Secret Book, the only strange thing in the cultivation world, is a precious and invaluable treasure of heaven and earth for any cultivator! The heart of the Thundercloud Daoist also twitched violently, and he just guessed at random. Unexpectedly, his guess was true! Although I don't understand how Zhang Yuan got the alchemy Mahayana cheats, what does it matter? In short, Zhang Yuan has obtained the inheritance of the alchemy Mahayana secret book, and has obtained all the understanding and experience of the tens of thousands of ancestors who have cultivated to the profound Dan Dao in the Hundred Herb Sect, which is the most important thing!
